DODECANDRIA. 425 



genus as to stamens and styles, which 

 therefore afford good marks to discriminate 

 the species. 



Class 11. Dodecandria. Stamens 12 to 19. 

 Orders 6. 



1 » M-Qnogynia. A rather numerous and very 

 various order, with scarcely any natural af- 

 finity between the genera. Some of them 

 have twelve, others fifteen or more stamens, 

 which should be mentioned in their cha- 

 racters. Asarum, Engl. Bot. t. 1083, and 

 the handsome I.ythrum Salicarid, t. 1061, 

 also the American Snow-drop-tree, Halesia, 

 not rare in our gardens, may serve as ex- 

 amples of this order. Sterculia is very 

 properly removed hither from Gynandria 

 by Schreber and Willdenow, as its sta- 

 mens are not inserted above the germen. 



2. Digynia consists of Heliocarpus, a very 

 rare American tree with a singularly fringed 

 or radiated fruit ; and Agrimonia, Engl. 

 Bot. t. 1335. The latter might as well 

 have been placed in the next class, with 

 which it agrees in natural order.
